I would like to change some Book2 value with respect to Book1's value.
 
Macro code in Book1:
Dim i As Integer
Dim k As Integer
k = Range("Z1")
For i = 1 To k
    If Cells(i, 22).Value = "Yes" Then
        Windows("Book2").Activate
        Cells(i, 11) = ""
        Cells(i, 13) = ""
    End If
Next i
